I dislike goto's too. I wrote those goto's in the original code. There
is a metodology in how they are used and their only purpose is to keep
state when we run out of buffer space without having to split and blurr
the main algorithm. I do not know of any clearer way of doing this
without continuations (lisp, python) or lazy evaluation (haskell), but
if you do I would love to read it :)

Thanks for maintaining that code, if you have any problems with it I can
try to take a look at it again.
